Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481786, here are decompositions:

17 + 481769 = 481786
89 + 481697 = 481786
113 + 481673 = 481786
167 + 481619 = 481786
197 + 481589 = 481786
317 + 481469 = 481786
353 + 481433 = 481786
443 + 481343 = 481786

Showing the first eight; more decompositions exist.
